Application filed September 21,1903. Serial No. 114,021. (No model.) I

To @ZZ whom it may concern.:

Be it known that I., NELSON GooDYEAn,a citizen of the United States, and ai resident of New York city, New York, have invented certain -.new and useful Improvements in Acetylene- Generators, of ,whichthefollowing is a specification accompanied by drawings.

This invention relates to acetylene-generators, but more particularly to portable generators.

The objects of the invention are toimprove upon the construction of portable aeetylenegenerators,simplify their parts, and increase their efficiency' of operation.

Another object of the invention is-to enable a charge of carbid to be readily supplied to the generator and the residue removed therefrom when used up. A

Further objects of th'ein'vention will hereinafter appear; -and to these ends the invention consists of a generator embodying the features of construction, combinations of elements, and arrangement' of partsv having the general mode of `operation substantially as hereinafter fully'described and claimed in this specification and shownin the accompanying drawings, in whieh-" Figure 1 is asectional elevation of agenerator embodying the invention. Figs. 2, 3, 4; and 5 are sectional elevations of different forms of the generator, all embodying the invention. Fig. 6 is a side elevation of a carbid-canister such as used in the generator shown in Figs. 1 and 5. Fig. 7 is a side elevation of a carbid-canister' such as used in the generators shownf'in Figs. 2, 3, and 4:. Fig. 8 is a plan-view of one o'f the carbid-camisters. Fig. 9 is a perspective view of the grating shown in Fig. 3. Fig. 10 is a plan View ofthe generator. Fig. 11 is a bottom plan view of the device for holding the can- Fig. 12 is a detail View of the hook used with the device shown in Fig. 11.

Referring to the drawings, A representsa the spring-clamps C, tothe easing, and atple K for the attachment of a tube.

. the filter-bag distended.' K

ing tube' D, havinga nipple Eat its lower end, as -shown in Fig. 1, `said nipple being 'surrounded with a washerF, in this instance shown conical and made of rubber. On the cover B and surrounding the upper projecting' end of the tube D is an outwardly-screwthreaded projection G, with which the inwardly -screW- threaded cap H cooperates.

The cap H serves the twofold object of supfabric and supporting the gas-cockJ and nip- Within the filter I' isshown a rod L for maintaining The charge of carbid is adapted to be contained .Within the canister O.- The canister O is provided With apertures P in its ends and one of which the conical plug or washer F is adapted to fit, the washer Q also being of rubber in this instance. The washer Q surrounds an upwardly-extending tube R, provided with an upper apertuse and a cap T at its upper end.. The tube'R and washer Q are carried by a hinge-arm U, hinged to the downwardly-depending hollow arm or tube V, which is connected, as shown, at its upper end to theI downwardly-extending tube D and supported from the 'cover B by a suitable support W. A spring X, connected tothe cover B, is arranged within the casing and is prol vided with a link Y, having a ring Z at its lend adapted to engage the hooked end of the casing and in operative relation with the parts ofthe apparatus, the cover B is first removed .and with it the parts attached thereto. The

plugs F and. Q are then inserted within the apertures P 'in the eanister and the hinge-aria U secured in positon'by means of the li'nk Y. The cover B and depending partsgtogether casing-A'.- The cover is provided, as shown,

The cock JA is closed and the casing is filled with'water. The confined air .inthe canister jand thetubes andI preuntil the coclz'J .isf opened. When theicock J is opened, thewater rises. through th'egtubevv R'fand'drip's 'downwardly tl-nouglgi .the hole S and. tttankjs'the'eafjtidgatthe "bottom ofthegas generated passes through The lowe- Dertien Qiv the .tube V. is provided with' the apertures' e, "as shown. :fAn. excess ofpressure will f foree the water downwardly in the tube Valid permit the gas Vto 'escape fromthe `apertures e, thus` affording a safety- Y 1. i The canis theremovable' seals f, soldered over the openvent;I

a downwardly-depending neck-D is provided withI an lenlarged 'lower portion .g, openat the bottom and having .inwardly-extending springs .L .for gripping the canister c' and holding it in position. `In this' instance the cani'ster-is profvided with hilt one opening? in 1,

oneV end, 'the other 1end/being" closed'.' T Atube j, having awasher lI?, isv first inserted in jthe,

'Opeing P audthenthecanister isthrust dpi' wardly within the Aenlarged portion y; connected to the sleeve D.- VThe tube j, as shown, is p rovided with an upwardextension k, adapt ed to. surround the' filter. An upper wateraperture l and lower gas-apertures o are provided in the tube j. According to this construction thewater within the casingA arises around the canister and drips through the openingl in the tube j. .The gasgenerated may passF through the tube y' and through the openingo and rising through the filter passes to the gas-outlet. In this instance the cover B is secured by means of a band or joint p to the `casing AL. i v

In Fig. 3-the canister q is provided with one opening 1), as before, and in order to permit Water t have access to the interior of the canister an aperture 1' is provided in the side thereof. This apertureris sealed with a removable seal s. (Shown in dotted lines in Fig. 3 audshown in full lines in Fig.. 7.) W hen the' canister is to be used, this seal is removed and the water arising around the canister may drip througlithe aperture r upon the carbid. In Fig. 3 a larger screen t is used than` in the other figures, although the smaller screen is tofbe preferred. l The "object of using vthe large screen is to preventthe carbid from clpggingthe.drip-opening. Other forms of screnscouldbe used for thepurpose.

The other ,end of thelanisteru is not provided with an apar# rrnally; but, when the charge is to be usar. thecaniste to permit the escape ofgasJ- Dispiovided with the inwardly-screw-thrle'aded end f1o, 'having`the gas-apertures w' therein. 'In order vtojsecurethe canister O in position,

a' tube y. provided with screwthreads at one end, isthrust through the openings P inthe canister andthe screw-threaded end'of the tube y is engaged with the threads of the inwardlyscrew-threaded end w'. A thumb-piece z upon the tube g] permits the tubeto bfefrnahole {viS 'punched through thetopof nipulated, and a suitable washer e' is arranged between -the thumb-piece z and the bottom of the canisterl A'drip-apertu-re y is provided tion the water rises through the tube y and drips through-the opening y', the operation of the apparatus beingas heretofore described.

Obviously some features of this invention may be used without others, and the invention may be embodied in v iglely varying forms.

Therefore, without l1 iting the invention to the construction shown and described nor enumerating equivalents, I claim and desire tosecure byLetters Patent the following; A- carbid-canister for an' acetylene-generator'v having openings in the top and bottom,

a tube extending throughone Vopening into A the canister, with-a drip-opening therein, a
